Gulmohar (Delonix regia), also known as  Royal Poinciana or flame tree or fire tree is one of the most beautiful trees in the world. It is perhaps one of the oldest ornamental trees grown with one of the earliest records of cultivation in India.

The tree can thrive in almost all climate conditions except very dry or frosty climate.  Flowers bloom in between April and May and in around November the leaves start turning yellow and shedding. It has a shallow-root system, making it quite vulnerable to damage in storms.  The plant grows upto five feet per year and thus matures and develops pretty fast.  Flower color varies from light orange to deep scarlet and other intermediate shades too.
